RETIRED: Apple QuickTime RTSP Response Header Content-Length Remote Buffer Overflow Vulnerability

Risk

High

Date Discovered

November 24, 2007

Description

Apple QuickTime is prone to a remote buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied input before copying it to an insufficiently sized stack-based memory buffer. This issue occurs when handling specially crafted RTSP Response headers. Attackers can leverage this issue to execute arbitrary machine code in the context of the user running the affected application. Successful exploits will compromise the application and possibly the underlying computer. Failed attacks will likely cause denial-of-service conditions. QuickTime 7.2 and 7.3 are vulnerable to this issue; other versions may also be affected. NOTE: This BID is being retired because further analysis reveals that this is a duplicate of the issue described in BID 26549 (Apple QuickTime RTSP Response Header Content-Type Remote Stack Based Buffer Overflow Vulnerability).

Recommendations

Deploy network intrusion detection systems to monitor network traffic for malicious activity.

Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This includes but is not limited to requests that include NOP sleds and unexplained incoming and outgoing traffic. This may reduce the chance of this issue being exploited.

Run all software as a nonprivileged user with minimal access rights.

To limit the effects of a successful compromise, run all client software with the least privileges required to function.

Do not follow links provided by unknown or untrusted sources.

To reduce the likelihood of successful exploits, never visit sites of questionable integrity or follow links provided by unfamiliar or untrusted sources. Never handle files from unknown sources.

Implement multiple redundant layers of security.

Various memory-protection schemes (such as nonexecutable and randomly mapped memory segments) may hinder an attacker's ability to exploit this vulnerability to execute arbitrary code.
Currently we are not aware of any vendor-supplied patches for this issue. If you feel we are in error or if you are aware of more recent information, please mail us at: vuldb@securityfocus.com.
